My invention relates to a packing and merchandising device which may beinexpensively made from boxboard or other sheet material.

It is an object of my invention to provide a device of the characterindicated which may be employed with annular articles and serve not onlyto support the article and prevent detrimental deterioration of it, butalso to facilitate the handling of individual articles and their packingin shipping containers.

It is also an object of my invention to provide a device which willfacilitate the merchandising of the articles, and will serve to markthem with desired indicia, such as trade marks, manufacturers names,identifying data, directions for use, and the like.

These and other objects of my invention which will be set forthhereinafter or will be apparent to one skilled in the art upon readingthese speciflcations, I accomplish by that certain construction andarrangement of parts of which I shall now describe an exemplary.embodiment.

The exemplary embodiment was designed as a packing and merchandisingdevice for cleaning pads made of metal wool in an annular or doughnutshape. It will be understood, however, that my structures may be usedwith other articles characterized by a perforation in which my devicemay be engaged as hereinafter set forth. Small coils of wire or cordagemay be packed in this fashion, as well as assemblages of rubber bands,and other types of articles or sales units.

Reference is made to the drawings wherein Figure 1 is a plan view of ablank for my exemplary device.

Figure 2 is a plan view'thereof after tubing.

Figure 3 is an isometric view of a completed package.

Figure 4 is a cross section of the package.

In the formation of my exemplary device, by means well-known and currentin the folding carton industry, I provide a blank of cut, scored andpreferably printed boxboard, characterized by body wall members I, 2, 3and 4 together with a glue flap 5 in articulation.- One alternate pairof walls, in this instance the walls I and 3, are made very much shorterthan the remaining walls and have articulated to their ends flaps 6, I,8 and 9 as shown. The remaining body walls 2 and 4 are made very muchlonger than the first mentioned walls. Preferably, though notnecessarily, the ends of the body walls 2 and 4 are rounded as indicatedat I0. For economy of board I ordinarily make the length of the bodywalls 2 and 4 equivalent to the length of the re- 2 maining walls plustheir attached flaps. The extensions of the body walls 2 and 4 beyondthe ends of theremaining body walls will, however, be determined withrespect to the nature and dimensions of the article to be packed.

One of the longer body walls may be provided with one or more transverselines of score I I and I2. These score lines are not necessarily locatedin alignment with the score lines by which the flaps are articulated tothe body walls I and 3. In the event the article to be packed is readilydeformable it is advantageous to locate the score lines I I and I2appreciably nearer the ends of the wall 4.

The blank illustrated in Figure 1 may be tubed by being bent on a pairof longitudinal intermediate score lines with the adhesive attachment ofglue flap 5 to the free edge of wall 4, as will be readily understood.This tubing operation may be performed on any of the standard cartontubing and gluing machines known to the art.

The result is a tubular knocked down structure which may be shipped andstored fiat, as shown in Fig. 2. When erected or squared up. and theflaps 6, I; 8 and 9 bent over, the structure presents a rectangular bodywith an opposite pair of body walls 2 and 4 extending to their ends wellbeyond the rectangular body. Upon bending up the projecting ends of oneof the longer body walls (if necessary on the score lines II and I2.)the structure may be passed through an orifice in an annular or otherarticle, such as the pad I3 of metal wool illustrated in Figure 3. Whenthe ends of the longer body wall are released they will spring backsubstantially into coplanar position, leaving the annular article held,as it were, on a reel-shaped support. This will be apparent from Figures3 and 4.

The body of my structure is fairly rigid and thus gives support to theannular article where that article is easily crushed or distorted. Thelarge walls 2 and 4 lying on each side of the annular article furnishadditional protection and serve to mark the article. They may be printedwith whatever indicia or designs are thought advisable foridentification or display.

In the case of metal wool pads it will be evident that my device notonly serves to mark the pads, but acts to prevent them from losing theirshape,

becoming crushed and distorted. Where a quantity of pads is packed in asingle container, my devices keep the pads separate, preserve theirindividual entities, and prevent the pads from becoming tangled witheach other. My devices permit the stacking of the pads for storage,shipment or display. For reasons already set forth. ends, another spacedpair of said body walls havmy devices facilitate the individual handlingand ing end portions extending beyond the ends of sale of the pads; andthe display matter on my f the first mentioned pair of body walls, saidpackdevices enhances consumer appeal. ing device being in erectedcondition with said Modifications ,may be made in my invention 5 flapsbent over and said first mentioned walls exwithout departing from thespirit of it.
